Abstract
The invention relates to a system for securing a cover on a container by providing a retaining mechanism having a projection that is received by corresponding apertures and/pr cavities in the cover and container, thus preventing the rotation of the cover with respect to the container. The cover can include a projection, such as a gas outlet, by which the retaining mechanism can be anchored to the cover. A sealing assembly can be received in the gas outlet, and include a projection extending outward from the gas outlet thus preventing the removal of the retaining member until the sealing assembly is removed. Preferably, the sealing assembly also closes a gas aperture in the cover when inserted into the gas outlet.
Description
- The present invention relates to a rotation mechanism for sealing transport containers for liquids.
- An example of a clamping ring used for sealing transport containers is disclosed in the form of a lid for a pot in EP 1 215 138 B1, in which a pressure release device is provided on the lid and a locking ring fits around the lip of the pot for substantially creating a seal with the pot. A part of a securing mechanism extends horizontally from the pressure release device, and a bolt pointing downwards is provided on the end of the securing mechanism, wherein the bolt is received by an aperture in the clamping ring.
- This securing mechanism and others like it can have various shortcomings. The securing mechanism can become deformed, and it can be difficult to take apart the pressure release valve or the securing mechanism. Furthermore, in such a case it is necessary to replace the valve and the securing means, which is associated with considerable costs.
- Generally speaking, in accordance with the invention, a system and method for securing a cover onto a container is provided, including a visual verification that the cover is secured. In one embodiment of the invention, a retaining mechanism is provided which prevents the cover from being inadvertently lifted from the container, more specifically, from being rotated when in the locked position.
- Another embodiment of the invention provides a securing assembly for ensuring that the retaining mechanism cannot be inadvertently removed from the cover unless the securing assembly is disassembled or broken. A user is thus visually alerted to the risk, ensuring that the user either replace the securing assembly or take necessary precautions while handling the container.
- In accordance with a preferred embodiment, a retaining mechanism comprises a projection that engages a corresponding cavity or aperture in a cover, a container with which the cover creates a seal when in the locked position, and a latching ring, which maintains the cover in place on the container.
- The object of the invention under consideration is therefore to create a more reliable and economical system for securing a cover by latching a clamping ring than presently available.
- It is also an object of the invention to provide a system for securing a cover by latching a clamping ring providing a securing element that is not easily deformed.
- A further object of the invention is to provide a system for securing a cover by latching a clamping ring that is easy to use, that can be assembled and disassembled relatively simply.
- The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts, which will be exemplified in the construction hereinafter set forth, and the scope of the invention will be indicated in the claims.
- The invention accordingly comprises the several steps and the relation of one or more of such steps with respect to each of the others, and the apparatus embodying features of construction, combination (s) of elements and arrangement of parts which are adapted to effect such steps, all as exemplified in the following detailed disclosure, and the scope of the invention will be indicated in the claims.
- For a fuller understanding of the invention, reference is had to the following description, taken in connection with the accompanying drawings, in which:
-
FIG. 1 is a front elevational cross-sectional view of a container and cover in accordance with an embodiment of the invention; -
FIG. 2 is a partial view of a cover, fastener and retaining mechanism in accordance with an embodiment of the invention; -
FIG. 3 a is a partial view of a cover and fastener in accordance with an embodiment of the invention; -
FIG. 3 b is a perspective view of a retaining mechanism in accordance with an embodiment of the invention; -
FIG. 4 is a partial cross sectional view of a container, cover, fastener and retaining mechanism in accordance with an embodiment of the invention. - Certain exemplary embodiments of the present invention will now be described with reference to the drawings. In general, a system for securing a cover on a container is provided. In one embodiment of the invention, a fastener, such as a clamping ring, secures the cover in place and helps create a seal between the cover and the container. It is preferable for a seal to be created to prevent leakage, especially if the container is filled with liquid. In accordance with a preferred embodiment of the invention, the clamping ring covers the seal formed between the cover and the container, thus protecting it and helping to prevent it from being broken.
-
FIG. 1 is an illustrative depiction of a container generally indicated as 1 in which liquids can be held. Container 1 preferably has an outlet (not shown) proximate its lower end or on the lower area of the sidewall. Preferably, container 1 is suitable for being transported. For example, container 1 can have castors 8 as shown. Alternatively, container 1 can be transported using forklifts or the like, rather than being rolled. Container 1 can thus be formed as a transport container. - In accordance with the embodiment shown in
FIG. 1 , container 1 comprises atank 2, which has an opening generally indicated as 4 proximate its upper end.Opening 4 can provide access to the interior of thetank 2, for example, for maintenance work, cleaning or the like. It is common for opening 4 to be called a “manhole”. - At least during transport, it is preferable for container 1 and thus opening 4 to be closed, more preferably sealed, to prevent the contents of container 1 from spilling or leaking out of container 1. A
cover 3 can be placed on container 1 to closeopening 4.Cover 3 is preferably placed on aseal 6, which can facilitatesealing cover 3 andcontainer 2. Afastener 5 can be provided to apply pressure oncover 3 onto container 1 to keepcover 3 in place with respect to container 1 and can also shieldcover 3 andcontainer 2 where they meet. - Reference will now be made to
FIG. 2 , wherein a portion ofcover 3 and faster 5 is shown withgas outlet 7 and aretainer 10 are shown.Retainer 10 preferably preventsfastener 5 from being shifted out of place, and preferably, from being inadvertently released from container 1. In the example shown inFIG. 2 ,fastener 5 is placed on container 1 so that a notch generally indicated at 12 offastener 5 receives apin 13 of container 1. Oncepin 13 is received innotch 12,fastener 5, which can either be connected to or be independent fromcover 3, is preferably rotated, thus permittingpin 13 to enter a channel generally indicated at 12 a ofnotch 12. Therefore, oncefastener 5 is in this locked position, neitherfastener 5 norcover 3 can be removed simply by pulling at it. Rather,fastener 5 must be rotated untilpin 13 is no longer withinchannel 12 a ofnotch 12 before fastener 5 andcover 3 can be pulled away from container 1. - However, an additional verification that
cover 3 is properly in place is provided byretainer 10 in accordance with an embodiment of the invention. In the embodiment shown inFIGS. 2 and 3 b,retainer 10 comprises aprojection 11 which can be inserted into a corresponding aperture infastener 5. Preferably, container 1 has a corresponding aperture or cavity for receivingprojection 11. Therefore, whenprojection 11 is received byfastener 5 and container 1,fastener 5 is substantially prevented from rotating or shifting, thus preventing the inadvertent release ofpin 13 fromnotch 12. - Notches 12 and
pin 13 interact in such a way thatfastener 5 can be rotated into a latching position in whichcover 3 sits firmly on container 1 or a position in which fastener 5, preferably together withcover 3, can be removed from container 1. The interaction ofprojection 11 andfastener 5 and container 1, more preferably also withcover 3, substantially prevents rotation offastener 5, unlessprojection 11 has been removed. -
Cover 3 preferably includes agas outlet 7.Gas outlet 7 is preferably constructed and arranged to relieve excess pressure in container 1, or to limit the amount of excess pressure in container 1. Preferably,gas outlet valve 7 can release gas from within container 1 when a predetermined pressure is reached. - An exemplary embodiment of
retainer 10 extends towardgas outlet 7 as shown inFIG. 2 . As illustrated inFIG. 3 b,retainer 10 has afirst leg 10 a havingprojection 11,first leg 10 a extending substantially parallel to cover 3 asecond leg 10 b extending away fromcover 3, and athird leg 10 c having an aperture generally indicated at 19.Aperture 19 preferably can receive at least a portion ofgas outlet 7. In the embodiments shown inFIGS. 2 and 4 , whenretainer 10 is properly positioned to retainfastener 5 andcover 3 in place with respect to container 1,projection 11 is received by container 1 andthird leg 10 c is positioned such thatgas outlet 7 is at least partially received withinaperture 19. - In accordance with the embodiment shown in
FIGS. 2 and 4 ,gas outlet 7 comprises ahollow housing 40 and includes aplug assembly 14 therewithin.Plug assembly 14 preferably comprises aplug 22 which can substantially seal agas aperture 25 in container 1. As illustrated inFIG. 4 , top 30 exerts a pressure on aspring 23 and thus plugs 22 toward container 1 to closegas aperture 25. Alternatively, when the pressure within container 1 is greater than desired, plug 22 can be pushed outward in order to permit gas to exit container 1.Gas outlet 7 preferably comprises one ormore openings 26, more preferablyproximate cover 3. The gas escaping from container 1 can thus exit through the one ormore openings 26 to relieve the pressure within container 1. Once the desired pressure is achieved, plug 22 preferably substantially sealsgas aperture 25 again. It is to be understood that whereas aspring 23 is preferred, for example, because it permits the movement ofplug 22 without requiring the movement of a top 30 ofplug assembly 14, this selective movement can be provided in a variety of ways without the use of a spring. -
Top 30 preferably includes one ormore protrusions 15, andgas outlet 7 preferably comprises one or more top notches generally indicated at 16. According to an exemplary embodiment of the invention, plugassembly 14 is inserted intohousing 40 ofgas outlet 7 untilprotrusions 15 are received bytop notches 16, whereupon top 30 is rotated untilprotrusions 15 are sufficiently within top-notch channel 16 a. Thus, top 30 is substantially prevented from being removed fromgas outlet 7 by merely pulling it. Rather, top 30 must be rotated and then pulled in order to be removed fromgas outlet 7. - The combination of
protrusions 15 andtop notch 16 provide an additional benefit. It can prevent the removal ofretainer 10. Onceretainer 10 is positioned so thatgas outlet 7 is received withinaperture 19 andprojection 11 is sufficiently received by container 1,protrusions 15, which extend outwardly fromgas outlet 7, can prevent the removal ofretainer 10. - In accordance with an exemplary embodiment of the invention, a
bolt 31 provides an additional reassurance as well as a visible indicator thatretainer 10 is properly in place. In the embodiment of the invention shown inFIG. 2 , top 30 has agroove 28. When top 30 is rotated to and properly positioned, groove 28 aligns with one ormore bolt apertures 27 ofgas outlet 7. Therefore, onceretainer 10 and plugassembly 14 are properly positioned, bolt 31 can be slid through afirst bolt aperture 27, throughgroove 28 and through asecond bolt aperture 27, such thatbolt 31 is located withingroove 28 with a portion ofbolt 31 extending outward fromgas outlet 7. Thus top 30 can be prevented from being rotated unlessbolt 31 is removed or broken. This can thus substantially prevent the removal ofretainer 10 as long as container 1 is still under pressure. - Whereas
groove 28 can be preferable because it can prevent top 31 from being rotated to releaseprotrusion 15, it is not necessary. Alternatively, bolt 31 can be positioned above top 30, thus preventing top 31 from being removed without removing ordamaging bolt 31. - As described above, certain embodiments of the invention provide assurance that container 1 is properly closed, and a confirmation of the authenticity of the seal between
cover 3 and container 1, thus substantially preventing accidental opening and spilling of the contents of container 1. - Whereas
gas outlet 7 is illustrated as being cylindrical and extending substantially perpendicularly fromcover 3, it is to be understood thatgas outlet 7 can take other forms, such any extending at an acute or obtuse angle, being cubical, curved, etc., without deviating from the scope of the invention. Additionally,aperture 19 can be a different shape, for example, rectangular, oval, etc. without deviating from the scope of the invention. -
FIG. 4 illustrates an embodiment ofcover 3 andfastener 5 secured to container 1, whereinretainer 10 preventscover 3 from being removed from container 1. The embodiment of container 1 has aflange 20 that extends aroundopening 4. Aseal 21 lies onflange 20, and as shown,fastener 5 andcover 3 are pressed on to seal 21. As illustrated,fastener 5,cover 3 andflange 20 have apertures preferably aligned and suitable for receivingprojection 11.Projection 11 ofretainer 10 can be inserted through these apertures to preventfastener 5 from being rotated about container 1.Projection 11 is preferably covered byfirst leg 10 a ofretainer 10, which can protectprojection 11 from becoming deformed. - In the embodiment show,
first leg 10 a extends substantially parallel to cover 3 until it meetssecond leg 10 b at a substantially 90 degree angle, which then meetsthird leg 10 c at a substantially 90 degree angle. However, it is to be understood that the connections betweensecond leg 10 b andfirst leg 10 a and/orthird leg 10 c need not be at substantially 90 degrees, but can be an acute or obtuse angle. Alternatively, the connection can be gradual, rather than at a defined angle. Additionally, the connection betweenfirst leg 10 a andsecond leg 10 b can be recessed fromcover 3 andfirst leg 10 a can extend away fromcover 3, which may facilitate assembly. Furthermore, first, second and/orthird leg FIGS. 2 and 3 b, and can be separate pieces rather than one integral piece. - One method by which
fastener 5 can be removed in accordance an embodiment of the invention includes removingbolt 31 fromgroove 28.Top 30 is then rotated to releaseprotrusions 15 fromtop notch 16.Gas outlet 7 is thus made non-functional or is opened completely. The pressure exerted byspring 23 againstplug 22 is thus removed, and therefore plug 22 retracts away fromgas aperture 25. Any excess pressure in container 1 is consequently relieved, and the interior of container 1 is thus at ambient pressure. By removing theplug assembly 14,retainer 10 can be pulled away fromcover 3 until it is released fromgas outlet 7. Simultaneously,projection 11 is also pulled out of the apertures offastener 5,cover 3 andflange 20 untilprojection 11fastener 5 is released. Onceprojection 11 is removed,fastener 5 can be rotated to releasepin 13 fromnotch 12, after which fastener and thus cover 3 can be removed from container 1. - The invention can be particularly advantageous for transport containers in which the persons who fill the containers are not the ones who empty the containers. The latter are thus often not familiar with all the technical details of the transport containers. Therefore, a transport container that prevents faulty operation, such as opening the manhole when the container is under pressure, as provided in accordance with an embodiment of the invention, can be advantageous. The examples provided herein are merely exemplary, as a matter of application specific to design choice, and should not be construed to limit the scope of the invention in any way.
- This completely
removable retainer 10 can also facilitate replacement ofretainer 10 should the need arise. For example, ifretainer 10 becomes deformed, or broken, etc., a new retainer can simply be used and the unusable retainer discarded. This can also reduce maintenance cost by permitting partial replacement rather than the replacement of the entire cover or container. However,retainer 10 is preferably formed of a substantially resilient material that is substantially resistant to deformation, chipping, cracking, etc. - Thus, while there have been shown and described and pointed out novel features of the present invention as applied to preferred embodiments thereof, it will be understood that various omissions and substitutions and changes in the form and details of the disclosed invention may be made by those skilled in the art without departing from the spirit of the invention. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
- It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
